In partnership with MIT and Columbia's American Language Program, CCNMTL produced an online learning environment to support novice teaching assistants. TASK, the TA Strategy Kit, is a web-based tool designed to help teaching assistants, new faculty, and novice instructors become better teachers. TASK features short, annotated videos that model good teaching and effective interactions with students, allowing users to see concrete, practical techniques they can implement in the classroom immediately. Complementary text reinforces the points illustrated in the videos, discusses other effective strategies and tactics, and explores the theory and research that support the techniques suggested.
